| * Test Name: lstat03 |

| * Test Description: |
| * Verify that, lstat(2) succeeds to get the status of a file pointed to by |
| * symlink and fills the stat structure elements. |
| * |
| * Expected Result: |
| * lstat() should return value 0 on success and the stat structure elements |
| * should be filled with the symlink file information. |
